Description

I always wanted to do a rom hack by myself that was challenging and fun. I lost interest in playing Pokemon games because they were too easy, not challenging, and did dont have enough possibilities. The first rom hack I played was Dark Rising years ago.

It wasn’t perfect, but man, did I get a good challenge. Then I tried many others and absolutely LOVED Emerald Kaizo, which I must have played 5-6 times until I found the right team to finish the game. I wanted to do a Kaizo style game, but with specific ideas in mind (this is what you will find in this game)

Features

  • Every fight and pokemon moveset has been thoroughly reviewed.
  • This is the original Emerald game, same map but with:
  • Added difficulty (this time it’s more gradual but still difficult)
  • New starters (Mew, Jirachi and Victini): the game is still difficult, don’t get fooled by the starters
  • More than 400 species are available (including legendary that are accessible before Elite four)
  • There are Wild Pokemon in every city (grass or water) except Littleroot Town. See Encounter List document.
  • Some light Pokemon stats modifications (ex: Flygon/Haxorus have 600 in stats like other dragons, all dragon Pokemon evolve at level 30 and 50 (even Deino, Dreepy)
  • This game has most of the Pokemon from Gen 1 to 8 – You have endless team options to go through this game. Some gym leaders will have Gen 9 PKMN.
  • All Pokemon can evolve without trade (see documentation)
  • All moveset of every Pokemon has been looked at to make them appealing and fun. Every move that a Pokemon learns is because it can be learned based on the Pokemon Database. Ex: Golem cannot and won’t have Hydro-Pump
  • TM’s are reusable (Exception: Calm Mind, Bulk Up and Double Team TM’s are unavailable unless a Pokemon already learned it via moveset)
  • Cannot use any items during battle except berries or hold items
  • More dragons are available to catch before the 5th gym (Lavaridge Town Lady will give you a Deino Egg)
  • 3 new rivals have been added (Red, Noland, Greta & Tucker)
  • You can now Mega Evolve your Pokemon during fights (after getting the ring and Mega Stones at Lilycove Mart) – To Mega Evolve, press Battle, then start button and then select move – it will Mega Evolve
  • Trainers, gym leaders and elite four have been reviewed for optimal difficulty without being unfair (ex: they will not have 4 Mega Evolution already evolved Pokemon on their team, they only have the possibility to Mega Evolve one)
  • You have access to Full Restore, Max Revive, Max Elixir, Master Balls and Rare Candy at Oldale Town. PP Max are available at Foretree. All evolutions stones + Lucky Egg are available at Mauville City and Harbour Mail + Mega Evol stones are on 2nd and 3rd floor of Lilycove Mart
  • There is a Hard Level Cap for every Gym Leaders, some major fights and Elite Four + Champion. Pokemon will stop learning EXP when you reach that level cap. See Level Cap document.
  • Nuggets are worth 150 000$
  • Some TM’s and items are scattered throughout the map and often protected by difficult optional fights. Sharp Beak, Twistedspoon, Leftovers, Magnet, Dragon Fang, Spell Tag, Fairy Feather, Choice Scarf, Life Orb, Rocky Helmet, Heart Scales and TM’s. See trainer walkthrough to find them.
  • More Hisuian, Galarian and fan favorite (Annihilape) have been added in the game. There is also some Gen 9 encounter during Trainer fights.
  • No need to learn Flash, Strenght or Rock Smash. I have removed every rocks in Victory Road and Seafloor cavern (Archie). You will need a Pokemon with Rock Smash once in the game: to continue after Mauville City.
  • You will find many Legendary Pokemon after Victory Road in Evergrande City to help you go through the Elite Four. Players who attempt to Nuzlocke will be guaranteed to have a Legendary in this grass.
  • Elite Four Phoebe has been changed for Grass/Fairy type
  • There is an IMPOSSIBLE FIGHT in Meteor Falls against Stevens. You will have access to many more powerful Legendary Pokemon after Elite Four in the Desert Underpass location to help you fight Stevens. If you win please show us your team!
  • There is no after game content. The game ends after Elite Four Champion and Stevens.
